.CEMENTING MACHINE Application filed July 24, 1,929. seen o. 3 0,528,.

i This invention relates to a machine for applying cement to the toeportion of articles of footwear. 1

footwear, it is customary to apply a cap of rubber over the toe of thefabricupper. The cap of rubber is cemented tothe fabric. It has beencustomary heretofore to apply the cement manually to the fabric over thearea to be covered by the rubber cap and thereafter to press the rubbercap thereon so as to adhesivel-y unite the rubberlcap to the fabric. The.operation of applying cement manually has not been satisfactoryinasmuch as it reuires considerable manual labor, is liable to defectsarising from human error, such as an inadequate quantity of cement orthe improper distribution of the cement overthe fabric or spreading thecement beyond the area to be coveredby the cap of rubber therebyrendering the article of footwear imslghtl y. To reduce the cost andincrease the rapidity and render this operation of apply ingcement tothe toe of the shoe more satisfactory is an object of this invention.

"It is the vob'ect of this invention to provide a machine w ich willperform the function of applying cement to the toe of a fabric upper. Itis also an object of this invention g to providea toe cementing machinein which a bead .of cement is applied across the toe which delineatesand sharply marks ofl' the area over which the cement is distributed. Itisalso .an object of this invention to pro- 5 vide a machine which willthoroughly distribute cement over the area so delineated. Otherobjectsand advantages of the present invention will appear from thefollowing detailed description taken in connection with m theaccompanying drawings, in which Fig. ,1 is a side elevation of theessential parts of the machine with parts broken away. Fig. 2 is adetail view showing the brush and cup partly in section. m Fig. 3 is afront elevation of the brushand I n of the mechanism shown in 4..

to be applied to the shoe.

According to my invention anarticle of fabric footwear 1 which has beenlasted and a to which the toe cap is to beapplied is brought In the artof manufacturing rubber fabricinto contact at its'toe portion with therim of a .cup 2. An adjustable supporti3 suitably mounted upon theframeof'the machine is provided for properly su'pportinglthe article offootwear 1 relative to the cementapplyirig parts of the machine. Theedge of the cup 2 serves to apply a line'or beadof cementacross Thisline or bead o-f the toe of the shoe. cement provides a relatively thick.depo sitio'f cement along that lineso as to securelynnite the fabricand the margin'of the toe cap later of cement also serves to mark offand delineate the area over which theceinent is distributed. I I The cup2 is mounted for rotation in aeasing 3. :Shoulders on "the cup andcasing respectively as indicated at serve to provide one bearing facebetween the cup and casing and theshoulders as indicated at 5between thecup andgback plate 6 securedtothe cas ing serving to form the otherbearing surface between the cup and the casing. I i The cup 2 isprovided with a ring gear T'With which .meshes the pinion 8 for drivingthe cup in rotation. The pinion 8 is fixed upon shaftQQnpon which isslidably, keyed 'the clutch member 10 which v,coo iierates with clutchmember, 11 rigidly fixedto ashaft 12 driven in rotation from anysuitable source of power, such as the motor 13. and red-11ctiongearl.

Cement is provided from suitable source ofsupply as the cement tank 17 connected with the box 16 through the pipecone nection 18. A scraper'plate l9 removesthe excess cement from theedge. of thecup which excess cement is carried off through-a suitablespout 20. 1 f; I

In order satisfactorily toqunite a rub-bertoe" cap with the toe of thefabric upper it is necessary that cement ;be distributed over the entireareato which the/toe cap-is united. .111

The line ,or bead V order to effect such distribution of cement, a brush21 is positioned within the cup 2 in a manner such that it may be movedover the toe of the shoe to spread cement thereover. The cement may besupplied to the brush directly through any suitable pipe connection, notshown, or the overflow of cement from the edge of the disk 2 may besufficient for.dis-' tribution .over the toe of the shoe, or the cementpresent on the parts of the shoe adjacent the toe due to previouscementing operations may be availed of for distributionover the toe. Thebrush 21 is mounted on arm 22 which is rigidly fixed to the shaft 23which rigidly carries pinion 24, the shaft 23 being mounted for rotationin thecasing 3, and the cup 2 beingopen from the back so as to permitthe arrangement of the brush 21 therein as shown in the drawings. abrush 21 are driven in oscillation by racks 25 which mesh with thepinion 24 and which are movable in and guided by ways 26. The racks 25are oscillated by the cams 27, the riders 28 being provided on theextremitiesof the racks for contact wtih'the faces of the cams 27. Thecams 27 are of 'such shape and so mounted upon their shaft that uponrotation thereof the racks 25 are moved in opposite directions, therebyeffecting the oscillation of the brush21. The upward movement of one ofthe racks 25 forces the other rack down wardly so as to maintain itsrider in contact with the corresponding cam 27.

In order that the article of footwear 1 may be held in proper positionwhile the bead -or line of cement is applied by the edge of'the cup 2,it is of advantage to stop the rotation of the cup at that time.Therefore the cup 2 rotates when the machine is not in use and isstationary when it is in use. When the toe of the article of: footwear 1is inserted within the cup 2, and before the rotation of the cup 2 hasbeen stopped and the article of footwear brought into contact with therim there of, it is of advantage to have the brush 21 stationary so thatthearticle of footwear may be more easily and accurately positioned.When the cement is actually applied, the article of footwear is broughtinto contact with the edge of the cup 2 which transfers its bead to theshoe and thebrush'21 is moved in oscillation across the toe of the shoeso as to distribute cement thereover. Therefore mechanism is providedfor simultaneously stopping the rotation of the cup 2 andfor setting thebrush 21 into oscillation. The description of such mechanism follows:

The clutch member'lO is provided with a groove in which rides the pin 28upon one extremity of one arm of bell-crank 29 mount ed for rotation onthe frame of the machine. The other arm of; the bell crank 29 isconnected with rod 30 leading to a foot treadle,

not shown. Upon the operation of the treadle, bell crank lever 29 isturned to open tsst54s The arm 22 and the clutch 1011 thereby stoppingthe rotation of the cup 2.

The bell crank 29 carries a dog 31 rotatably mounted thereon and springurged in a direction so as to engage with a ratchet 32. 'The ratchet 32is fixed upon shaft 33. which shaft rigidly carries a notched wheel 34.The wheel 34 cooperates with the latch 35 fixed upon shaft 36 suitablymounted for rotationon the frame of the machine. Shaft 36 carriesrigidly a lever 37, one end 38 of which is'provided with a cam edgewhich cooperates with pin 39 carried by clutch member 40. The clutchmember '40 is'urged" in a direction to effect engagement of the clutchby the spring 41. When the cam face 38 is in engagement with the pin 39,the clutch is held disengaged; Motion of thefoot treadle before referredto operates thebell crank 29 thereby rotating the notched wheel 34 whichthrough the'lat'ch 35 rotates'the lever 37 so as to release the clutch40 thereby setting the shaft 41 upon which cams 27 are mounted intorotation, the shaft 41 then being connected to shaft 42 driven from asuitable source of power such in this instance as the motor 13,reduction gear 14 and transmission system 15. Rotation of the cams 27effects the oscillation of the brush 21, as before described, slightlyafter the stopping of the. rotation of the cup 2. n a v It has beenfound most satisfactory inthe operation of the machine to drive thebrush 21' across thetoe of the shoe a limited number of times therebyadequatelydistributing the cement overthe" toe of the shoe and at thesame time materially shortening the opera{ tion. In addition it is ofadvantage to have the brush stop oscillating while the cup 2 is stillstationary so that the article of footwear may be removed from themachine without the motion of the brush 21 interfering. In order toeffectthis operationof the brush 21, the clutch 40 is of the limitednumber of revo' lutions type and'operates as follows Shaft 41 has a spurgear 43 fixed thereon, which meshes with the idler pinion 44 loosely'mounted for rotation upon the shaft 36 which in turn meshes withgear-'45 fixed'upon shaft 46 which rigidly carries camj47. When thelever 37 is lifted by pressing on the treadle of the machine, the chainof gears 43, and; cam 47 are set into rotation. The lever 37 is providedwith a'cam follower 48 which rides upon cam 47 and the shape of'the cam47 is such that in its rotation it maintains the'lever 37 in a raisedposition for a certain number of revolutions of the shaft 41 dependingupon the ratio of the gears 43-45. The spring and lever system 49 isprovided for urging the cam follower. 48 into contact with the cam'47;

When the cam 47 has completed its rotation, the lever 37 is rotated bythe spring lever system 49 so as to bring the cam face 38 into contactwith the pin 39 to effect the separation of her while it rotates.

rescue the clutch 40 and to stop the oscillation ofthe brush 21. As theshaft 36 carrying the cam lever 37 is rotated in its original position,the

with the tooth wheel 34. A catch 50 is carried by lever 51, the catchbeing urged into operative relation with the tooth wheel by the spring52, the catch 50 being for the purpose of preventing backward rotationon the wheel 34 when the foot treadle is released, thereby insuring acomplete forward movement of wheel 34 when foot treadle' is operateddownwardly. The article of footwear is then removed from the machine andthe cup 2 set in rotation by releasing the treadle. The cycle ofoperations may then be repeated.

While this invention has been described as being useful in applyingcement to the toe of an article of footwear, it is obvious that it maybe used to apply cement to other articles to which cement might besimilarly applied.

While one specific form of the invention has been disclosed by way ofillustration, it is not intended thereby to limit the invention theretoinasmuch as variations may be made in the machine without departing fromthe scope of the invention indicated by the fol lowing claims.
